FUEL-CHARGE-TREATIN'G DEVICE.

Original application filed October 12, 1922, Serial No. 594,216. Dividedand this application filed November 16, 1922. Serial No. 601,283.

To all whom it may concern:

Be it known that I, VIOLA Roo'r CAMnRoJ, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented new and useful Improvements in Fuel-Charge-TreatingDevices, of which the following is a specification. I

This invention relates to gas saving devices for internal combustionengines, and pertains particularly to devices for breaking up and mixingcombustible charges of fuel and air.

This invention is an improvement on the type of gas saving devicedescribed in the patent to Lampert 1,192,435, issued July 25, 1916,which patent provides for an article to be inserted between carbureterand the intake ports of an engine, the device including a metal platemember having a coiled spring cone mounted over an opening in the platemember, and having its base coil fixed t0 the plate member, theremainder of the cone being unattached and free to vibrate. In theLampert device, the plate is of solid material; has the general contourof a gasket; and is used between adjacent flanges of pipe ends. Themetal wall ofthe opening in the Lampert device is provided with anannular groove to receive and hold, by the expansive spring action, thelargest or base coil of the spring cone.

The general object of the present invention is to improve on the Lamperttype of device, and at the same time, retain the advantageous featuresof the freely vibratile spring cone.

One of the features of the invention relates to the improved means forso securing the base coil of the spring wire to the supporting platethat the coil cannot be loosened or separated accidentally from thesupporting plate, due. to the vibrations of the spring or the jolting orvibration of the engine. Another feature is the combinationof the spiralspring with the standard asbestos copper gasket, su plemented andmodified by the particular astening means for holding the spring overthe gasket opening.

Another feature is directed to the particular shape and mounting of thespiral spring cone, which may be compressed to occupy the space of thethickness of the gasket or plate in the opening of which it is mounted.This design makes it possible to insert the plate or gasket and springsidewise into position between adjacent pipe ends without necessitatingthe wide separation of the connection, it being merely necessary toloosen the connection sufficiently wide to insert the thickness of theplate or gasket. After such insertion, the spring cone is then free toassume its normal conical shape, and to serve in breaking up theincoming charge of the fuel mixture. This feature is particularlyimportant because of the ease by which the device may be installed. Byusing an asbestos copper gasket of ordinary thickness, and having thecross-sectional diameter of the material of the spring no greater thanthe thickness of the gasket, the device may readily be inserted in anyengine intake line without requiring modification of the engine parts.

The device of the present invention may be inserted at any connectionbetween the carburetor and the inlet ports. Satisfactory locations havebeen at the engine and at the carbureter ends of the intake manifold.The apex of the cone may extend in-either direction, according toconvenience, provided it does not interfere with the engine parts.

The above and other features and advantages of the device of theinvention will be described and claimed in the following specificationand claims, and illustrated in the accompanying drawing, in which:

Figure 1 shows a sectional view through a form of the device, includingan asbestos copper gasket, in which an annular ring holds the lower andlargest coil of the spring in its position adjacent the wall of theopening through the gasket. In this form, the ring is a separate memberand extends from one face of the gasket through the opening and alongside of the opposite gasket face;

Figure 2 shows, in section, the gasket illustrated in Fig. 1, but withthe conical spring compressed into the plane of the gasket, illustratingthe compressed position in which the device is adapted to be insertedbetween adjacent pipe and flanges;

Figure 3 represents a top plan view of the gasket and retaining ring, asshown in Fig. 1, but with the spring removed;

Figure 4L represents a top plan view of the conical spiral spring andgasket illustrated in Fig. l; and

Figure 5 represents a sectional View through one form of the device,showing the conical spring having its lower and largest coil heldbetween opposite metal faces of an asbestos copper gasket, the in-'termediate asbestos portion being" spaced back from the central openingto provide space for the reception of the spring.

Referring in detail to the various'figures of the drawings, likenumerals refer to like parts in the different figures.

1 is a spiral spring member formed in the shape of a cone, and sodesigned that it may be compressed to a plane having the thickness of across-section of the material. of the wire, as illustrated in Figure 2.The apex of the cone is indicated at 1. The base of the cone is formedby the largest coil or turn of the spring wire and is indicated at 1*. 2represents a gasket member or plate upon which the spring 1 is mounted.and which serves to hold the spring in its operative position wheninstalled in the intake line of aninternal combustion engine. 3 is acentral opening in the member 2, and 4 indicates end slots or openingsfor the reception of fastening bolts or studs by which the member 2 andits adjacent pipe connections are secured together. The spring 1 is heldin its mounted position with the axis of the cone in line with the axialcenter of the opening 3, and accordingly, thelargest coil 1 is heldadjacent to the wall of the opening 3, or actually in' the same planewith the wall of the opening.

The invention provides several different specific constructions forsecurely holding the coil 1 in its position about the opening 3. In thesectional views of the drawing, the upper face of the gasket member isindicated at 2 and the lower face is indicated at 2 and the asbestosintermediateportion of the gasket is indicated at 2. The asbestosportion 2 may be cut back away from the central opening, thus providingan annular space between the faces 2 and 2", as indicated at 5. Thelargest coil of the conical spring 1 is shown held in this annular spaceby its spring action, which tends to expand the lower coil l against thematerial 2 Thus, the spring is held bythe material 2 laterally, and bythe opposite metal material 2 and 2 on the top and bottom as shown inFig. 5.

In the form illustrated in Figs. 1-4 inclusive, a separate element 6 isillustrated, as engaging the under face of the gasket, passing throughthe opening and then being recurved along the upper face. Thisparticular holding means is thus formed as a ring having an annulargroove, the side walls of which enclose the largest coil 1 of the springcone, and also that portion of the gasket metal faces 2 and 2 nextadjacent the central opening 3. In each of Figs. 1, 2 and l an opening 7Will be seen, through which the upwardly extending spring projects. Theopening 7 is preferably elongated in order to' prevent undue distortionof the curvature of the spiral spring. It is desirable also that theopening 7 extend through the thickness of the member 6, sufficientlydeeply so that the coil of the spring projecting through the opening maybe p ompressed to the plane of the gasket, as in in assembling thedevice, it is intended that the end of the larger coil of the springcone be inserted into the opening 7 and the coil and gasket rotated withrespect to each other, so as to thread the largest coil. 1 into andaround through the space provided by the fastening member 6, the sidefaces 2 and 2 of the gasket and the asbestos material 2". In thearrangement shown in Fig. 5, the outward spring expansive action of thelarger coil 1 serves to hold it in the annular space between theopposite faces of the copper portion of the gasket.

For the insertion of the combined spring and lgasket into position in aninternal combustion engine, the invention contemplates the use of anyneecssary device, such as a pair of pliers, by which the spring may becompressed to the thickness of the material of the gasketbythe samemovement and by the same position of the implement which the operatoruses in holding the gasket. If the place of installation be readilyaccessible, and the spring readil compressible, the operator may use hislingers in compressing the spring and slipping the device sidewise, oredgevvise, in between the adjacent pipe ends.

The curvature of the spirals of the spring should be so arranged that aline drawn through the material of" the spring at any point and parallelto the axis of the cone will not pass through the material of the nextadjacent turn or coil of the spring, or any other portion of the spring.This description is presented as one way of stating thatthe conicalspring may be compressed to a given plane Without distorting any'oftheturns or coils of the spring in order toassume the plane position.

This'applicati'on is specifically directed to the particularcompressible featureof the spiral spring. Claims to theuse of'-a"sep'arate part are presentedin my copending application Serial No. 594,216,filed October 12, 1922, from Which this application has been divided.Specific claims directed 'to theuse of an extended portion of thematerial ofone face of the gasket, as the part'for holding the spring,are presented in my 'cop'ending application Serial No. 601,282, filedNovember 16, 1922.
